Don't forget the National gas appliance Product Quality Supervision and Inspection Center (Foshan), with the words "product" and "Foshan" added. Its predecessor was gas appliance Product Quality Supervision and Inspection Station. Gas appliance's production center is in the Pearl River Delta, so a large number of stoves are tested in Foshan Center, and the website of Foshan Center also has its own query system.
What is the relationship between Foshan Center and Beijing Center, and whether the test results of Foshan Center should also be uploaded to Beijing Center for inquiry is unknown.
